As we know that, Centripetal force is the force due to … WebSep 17, 2024 · What happens to the velocity of an object if the centripetal force is increased? The force can indeed accelerate the object – by changing its direction – but it cannot change its speed. In fact, whenever the unbalanced centripetal force acts perpendicular to the direction of motion, the speed of the object will remain constant.

WebDoes the centripetal force acting on an object do work on the object? a. No, because the force and the displacement of the object are perpendicular. b. Yes, since it takes energy... WebQUESTION 5 Which of the following statements is false for describing work done by a constant force? O The unit of work is the same as that of energy. If the angle between the force f and the displacement d is zero, the work done Wis W = fd. O If the constant force is parallel to the displacement, the work is zero. O The work is a scalar quantity.
